A surgical tool system including a laparoscopic surgical tool for heating, ablating, sealing, and / or dissecting tissue, a control system for monitoring impedance of the tissue during treatment thereof, and a tactile feedback system integrated onto a handle of the tool that generates relevant feedback from the control system in at least the form of haptic effects to the user. The tactile feedback alerts the tool user of changes in tissue properties, i.e., when the impedance of the tissue indicates that the treatment procedure is complete. In addition, the tactile feedback provided may supply information relating to the operating status of the control system to the user.

Products and processes for providing tactile sensations to input devices or electronic devices are provided. Input devices include mechanical input devices (such as, for example, mechanical switches) and non-mechanical input devices (such as, for example, touchpads). Tactile feedback is provided by using an actuator or other means in communication with the input device or electronic device. A controller may be employed to receive signals from the input devices and control the actuator. Tactile feedback to an input device or electronic device may be provided in response to one or more events or situations. Such an event or situation may be any one designated. Examples of such events and situations include the level of pressure placed on an input device; the availability or lack of availability of a function associated with an input device; and the function, menu, or mode of operation associated with an input device's activation. A variety of feedback types and combinations may be selected.

Method and apparatus for providing high strength, low frequency tactile sensations using an inertial actuator in a haptic feedback interface device, such as an actuator driving an oscillating inertial mass. A commanded low frequency is modulated or combined with a higher frequency at which the tactile sensations feel stronger, where the resulting signal is used to output a tactile sensation at the higher frequency and convey the commanded low frequency to the user. One embodiment provides higher frequency pulse bursts at the desired low frequency wherein the higher frequency pulse bursts are at or near a resonant frequency of the actuator; other embodiments modulate or otherwise vary the amplitude of the higher frequency signal according to the desired low frequency.

An intragastric catheter provides a method of inducing satiety due to its presence in the stomach cavity. Efficacy is improved by the tactile sensation provided by a plurality of fingers that extend from the device. Normal peristaltic action upon the device moves the fingers relative to the stomach. The structure of the intragastric catheter reduces the level of precision required in placement of the device, and blockage of conduits to and from the stomach by the device is unlikely.

A skin stimulation system (200) is integrated into a piece of clothing or any type of wearable accessory (101, 101′) which is connected to a controlling device (109). The system comprises a variety of sensing means (105a-c, 105′) for input information. Actuators (106a-p) placed on or close to body of a person wearing this piece of clothing or wearable accessory (101, 101′) are used for generating (S104′) visual, auditive, tactile, gustatoric and / or olfactoric stimuli (e.g. heat, pressure, vibrational and / or electric pulses, etc.). The invention further specifies a new method for transmitting tactile information between different wearable computing devices (100, 100′). According to one embodiment of the present invention, a number of different actuator elements (106a-p) which are used for generating vibro-tactile sensations are integrated into a piece of jewelry such as e.g. a necklace (304), a bracelet, rings (900b) with a single or variable number of beads (900a), gemstones, etc. These actuator elements (106a-p) are embedded in detachable casings (306a1-a4) which are pivotable about their suspension axes. Each of said beads, gemstones, etc. or at least some of them includes at least one integrated actuator element (106a-p). The invention further pertains to a method for tuning (S901) key parameters of said stimuli by pivoting said casing (306a1-a4) about at least one axis so as to bring said actuator means (106a-p) closer to or farther away from parts of a user's body wearing said piece of clothing or wearable accessory (101, 101′). Said key parameters are e.g. the intensity, duration and / or frequency of said stimuli.

Method and apparatus for increasing the transmissibility of inertial forces produced by an inertial actuator on the housing of a tactile feedback interface device. A tactile interface device, coupled to a host computer, outputs tactile sensations to a user based on interactions and events occurring in a displayed graphical environment. An actuator produces periodic inertial forces, such as vibrations, and a compliant suspension couples the actuator to the device housing. A compliance of the suspension is selected such that the suspension magnifies the periodic inertial forces for a particular frequency range of the inertial forces. The magnified inertial forces are transmitted to the housing to be felt by the user.

An interface device providing haptic feedback to a user is in communication with a host computer. The device includes a housing, at least one sensor for detecting user input, and an actuator assembly. The actuator assembly includes a grounded flexure suspension coupled to an inertial mass which moves when the actuator assembly is energized to cause inertial sensations. The inertial mass includes a pole piece surrounding a magnet, and a grounded coil between magnet and pole piece causes the motion of the inertial mass when current is flowed therethrough. Another embodiment provides directional haptic feedback to a user and includes at least two actuator assemblies oriented such that the inertial masses oscillate substantially orthogonally, and can be controlled to output the inertial sensations approximately along a single axis having a desired orientation.

A universal tactile feedback system for computer and video game systems is disclosed which provides real time tactile feedback to enhance a user's experience while interacting with a computer / video game or simulation. The tactile feedback system operates both in host-independent and host-dependent modes, thereby allowing the system to function even when no accommodation is provided by the game or simulation system that is being used. The host-independent mode is responsive to the audio signal that is typically generated by a computer or video game system while it is executing a game or simulation. The host-dependent mode is responsive to control commands specifically generated by a computer or video game system while it is executing a game or simulation. The tactile feedback system then creates tactile sensations primarily via controller-based tactile sensation generators, such that the user feels physical sensations corresponding to events occurring within the game or simulation in real time.

A web browser displays historical information about hyperlinks shown on web pages. Initially, a computer receives user instructions to download an internet web page, and begins the download. The computer identifies any hyperlinks present in the web page, and for each hyperlink, analyzes the hyperlink with respect to any of the user's past visits to the hyperlinked address. Analysis is performed with the following steps. First, the computer determines whether the user has previously selected that hyperlink, such by “mouse clicking” on the hyperlink. If so, the computer consults a database to identify characteristics of the underlying data obtained from past visits (or attempts) to the hyperlinked address. These characteristics are input into a presentation table to derive various enhanced presentation attributes for the hyperlink. The presentation table maps between each possible data characteristic and a corresponding enhanced presentation attribute. Presentation attributes may relate to text, graphics images, videos, sound, tactile sensations, etc. Ultimately, the computer displays the downloaded web page, each hyperlink with its enhanced presentation attributes.
